This website attempts to score audiophile loudspeakers based on:

• radiation/dispersion pattern
• type and shape of enclosure
• low frequency bandwidth (at -3dB)
• high frequency bandwidth
• mid freq. drivers moving mass
• sensitivity
• type of crossover
• servo controlled woofers

Loudspeaker models obtain a score from 0 to 15 on each of the first 6 qualities and 0-5 points on the last two. Each of those qualities can be given a weight, so the final score depends on which qualities are more important for the listener and which are less.

I've assigned 100% more weight to quality 1 - dispersion and 50% less to quality nr 4 ( high frequency extension) and nr 8 (crossovers). The user can assign his own weights. The enclosure score is an average of enclosures where mid and low frequency drivers are housed, as many models have different enclosures for these drivers.

The structure of this scoring system is based on the following assumptions:

• dispersion pattern is the most important characteristic as it has capability to interact in many ways or not to interact at all with room acoustics. In most cases, the frequency response in room varies much more depending on the dispersion than on the frequency response of the speaker itself,
• speaker's enclosure is capable of contributing greatly to the distortions generated by the whole system, as enclosures can have resonances, standing waves inside of them and diffractions problems,
• High frequency extension measured in kHz of bandwidth is not as strongly influencing the total sound quality as low freqency extension or other factors. For this reason its score range is smaller - from 9 points to 15, on top of that it is given a weight of 0.5 instead of 1. All in all, the difference between 100kHz and 20kHz extensions translates into only 3 points higher score out of total maximum 100 points. Ability to reproduce higher frequencies is also an indication of lower moving mass of the high freq. driver, which is a quality of itself, more beneficial in the ~10kHz-20kHz region,
• Mid freq. drivers moving mass has impact on impulse response, however (1) the type of crossover (active of passive), (2) sensitivity also play a role, but these factors are not yet included into a comprehensive scoring method in this area. However these two factors are covered in two separate criteria anyway.
